The Earth's Magnetism

What is the angle of dip at magnetic poles of earth ?

Assertion: The geographic north-pole does not coincide with the magnetic north pole.

Reason: The axis of the hypothetical dipole inside the earth is tilted by approximately $11.3^{\circ }$ with respect to the axis of rotation of the earth.

The south pole of earth's magnet is in the

The magnetic field lines go inside the earth near the:

The axis of rotation of earth passes through:

Geographic north pole is near the:

The Earth's magnetic field at a certain place has a horizontal component of $0.3 \text{Gauss}$ and a total strength of $0.5 \text{Gauss}$. The angle of dip is

At a certain place, the angle of dip is ${60}^o$ and the horizontal component of the earth's magnetic field $\left(B_H\right)$ is $0.8\times {10}^{-4} \mathrm{T}.$ The earth's overall magnetic field is

At a certain place, the angle of dip is ${30}^o$ and the horizontal component of earth's magnetic field is $0.50$ oersted. The earth's total magnetic field (in oersted) is

The relation between $B_h, B_v$ and $B$ is ________.

The vertical component of earth's magnetic field is zero at:

A place where the vertical components of Earth's magnetic field is zero has the angle of dip equal to

Let the magnetic field on earth be modelled by that of a point magnetic dipole at the centre of earth. The angle of dip at a point on the geographical equator is

At a given place on the Earth, the angle between the Magnetic meridian and the Geographic meridian is called.....

The lines of force due to earth's horizontal magnetic field are

At a place the true value of angle of dip is $60°$. If dip circle is rotated by $\mathrm{\varphi }°$ from magnetic meridian, the angle of dip is found to be ${\tan }^{-1}\left(2\right)$. Then the value of $\mathrm{\varphi }$ is

The tangent galvanometers having coils of the same radius are connected in series. A current flowing in them produces deflections of ${60}^{\mathrm{o}}$ and ${45}^{\mathrm{o}}$ respectively. The ratio of the number of turns in the coil is:

Assertion: A freely suspended magnet points along the north-south direction.

Reason: Since the earth behaves as a magnet.

Assertion: A freely suspended magnet points along north-south direction.

Reason: Since earth behaves as magnet.

The Earth's magnetic field at a certain place has a horizontal component of $0.3 \text{Gauss}$ and a total strength of $0.5 \text{Gauss}$. The angle of dip is
